Structure and Sealing Principle
● Mainly composed by rotating ring (part 1), floating ring (part 2), static ring (part 3), and
several o-ring (part4, 5, 6, 7, 8).
● The static ring (part 3) is fixed to the chamber through the stator o-ring (part 4), and a
oil return channel directly below the oil storage tank.
● The rotating ring (part 1) is fixed to the rotor through the rotor o-ring (part 5), and the
floating ring (part 2) is driven to rotate by o-ring (part 7), forming several 90° bending
and buffering chambers. Impurities from the outside are discharged through the drain
tank directly below by gravity and centrifugal force.
● The special structural design locks the static ring, rotating ring, and floating ring into
one unit, and the unique coalesce ring (part 8) design ensures that the oil mist can
effectively condense and reflux under oil mist lubrication conditions; The floating o-ring
(part 6) is equipped with a unique groove design on the floating ring, ensuring that it
acts as a static seal when stationary, achieving sealing between the bearing and the
external environment; During operation, the floating o-ring "lifts" under the action
of centrifugal force, greatly reducing wear, and the expansion gas generated in the
bearing cavity is safely released.

Quality Assurance
The whole set of bearing protectors shall operate continuously without faults for no less than one major overhaul period, and it is generally recommended to replace them every three years.
Special Note
Bearing protectors are different from contact seals, the model B8 cannot be used for pressurized working conditions. We can customize products with various materials and structural types to comply with the individual needs of customers.
Recommended Applications
● Pump
● Gearbox
● Blower
● Motor
● Other Industrial Rotating Equipment
Technical Service
Provide on-site technical services and operation training, and guide on-site installation, debugging and maintenance. The supplier should promptly respond and solve any problems that arise during operation and maintenance.
